Dynamically compensated edge detectors for single point web guide accuracy ─ using ultrasonic or infrared technology.

Point Source edge detectors utilize a unique two beam system that continuously monitors the energy transmitted, while automatically compensating for minute environmental changes to maintain consistent guide point. This means improved web accuracy and reliability with less downtime.

Even in the harshest environments, no other edge detector gives you more accuracy and reliability.

Specially designed compensated ultrasonic versions are available for high temperature applications up to 500ºF (260ºC).

Stainless steel and waterproof options are available for wet or harsh environments.

The advantage of dynamic compensated technology

Two beams of pulsed energy are transmitted across the detector gap.

The amount of energy received by the Edge Detection Sensor is converted to a digital web position signal. The amount of energy received by the Compensation Sensors provides a continuous reference signal to eliminate guide point drift due to changes in temperature, humidity, dust, dirt, ink overspray, web flutter, passline variations or other environmental factors.

As environmental conditions change, the Compensation, or Reference Beam, monitors the conditions in real time and proportionally adjusts the web detection beam to maintain the original guide point.
